Bill of Materials

RisksCrash

PreventionProgressive build process. Testing, testing, testing!

Interface to helicopter is only theoretically known.

Get the hardware figured out early. Testing the interface thoroughly before flight.

Not 100% sure we’ll get the helicopter and stabilization kit

Beg, borrow, and steal!

Loss of link and high latency

Design aircraft software for autonomous flight. Use fail safes (timed hover and land) for complete link loss.
